What in God's name are you wanting to know? As long as you bought the app you never need to buy the app again. You need to keep the same apple id, but that is the only requirement. You are making this more difficult than it needs to be.
Not sure what you mean. Your Apple ID has nothing to do with the capacity of your iPhone.
A 128 GB phone has approx 5 gb used for the operating system and included apps, leaving 123-ish for the user.
Most people will never fill up 32 GBS, which can easily hold hundreds of pictures, songs and plenty of other data.
Becky, please sign up for an iphone class with Apple. The more questions you ask the more apparent it is you don't know how to use the device, iTunes or iCloud.
The only time I would really push for a person to get at minimum the middle capacity iPhone (in this case 64 GB) would be if they like to use their phone with movies and record a lot of video (or any other data hogs). In those instances, especially if you don't have unlimited data and you aren't always on wifi, it behooves you to have more data than you imagine using. It's much easier than people may think to fill up even a 64 GB iPhone. Plus, if you already have an iPhone that should help you determine if more space is necessary based on your use of your current size (or lack of use if you've ever felt hindered by the capacity).
I just wish the OP could be a bit more clear on why they seem to think their Apple ID needs to be different for each of their devices or what they think the issue really is. Their line of questioning seems to suggest that they just don't have a true understanding of Apple IDs as they apply to their devices which is a little surprising since they appear to have at least 2 devices currently and should have a basic understanding of how the Apple world works in regard to it (unless of course they just got both devices).
Random questions should be directed to Apple community support forums. Questions here should relate to Apple on Verizon. Capacity of a phone she want to buy a year from now is not, nor should be a question asked here.
i Vote we close this thread.
